STELLAR LIGHTING SCR-1 Intelligent Stair Lighting Set Instruction Manual

STELLAR LIGHTING SCR-1 Intelligent Stair Lighting Set

Stair lighting control unit

These motion sensor-activated LED stair lights switch on automatically to light up your stairs when you reach the top or bottom step.

Control unit SCR1 switches the lights for all stairs together. Control unit SCR2 switches each step individually, giving a sweeping motion up or down the staircase. Both controllers turn on the lights together, by gently fading out.

This document explains how to install and operate your control unit.

If you purchased the stair lighting kit without lights, please consider the following specifications to ensure the purchased lights are compatible with the controller:

• 12 V lights only
• lights should be dimmable
• Our recommended LED light strip: SMD 3528 60LED/m with 4,8W/m
• Synchronized (SCR-1) controller: 100W total
  • DO NOT EXCEED 18m with these LED strips (SMD 3528 60LED/m)
• Cascading (SCR-2) controller: 2-20 lights, 9.6 W per light.
  • DO NOT EXCEED 180cm length per output with these LED strips (SMD 3528 60LED/m)

Before starting the installation, please check the contents of the box to make sure all components are there and read these instructions in full. Before undertaking the permanent installation, we recommend testing your set to prove its operation.

1. Decide on the location for your control unit and power supply. Both are designed to fit on a DIN rail (optional) for ease of installation.

2. Choose the instruction that matches your lights.
   a) Strip lights with profiles: Attach the profile to the stairs, according to your chosen profile. Note that profiles can be cut shorter if necessary.
   All profiles are fitted by removing the diffuser, drilling the aluminium at suitable points (depending on your installation site) and screwing the profile to the stairs.
   Important note!
   While cutting, drilling or making recess for the screwheads for the profiles, a small amount of metallic chip and debris will remain in the profile. This can cause small short circuits over days/weeks/months and can result in the LEDs on the strips to fade out or stop working. Therefore, it is very important to thoroughly clean the profiles, before placing the LED strips inside.
   b) Spotlights: The spotlights are suitable for surface-mounted and flush-mounted installation
   The surface-mounted frame can be removed if the lights are flush-mounted.
   The dimensions of the surface or flush-mounted can be seen on the diagrams below.
   

3. Position the motion sensors at the top and bottom of the stairs so that the person entering the staircase crosses the beam. The height of the motion sensor can be chosen to suit the installation site. Low sensors are discreet; placing sensors higher allows pets to pass underneath the beam so that they do not activate the lights.
   We recommend installing the motion sensors on the baluster side and directing the signal towards the wall. The motion sensors are designed to have a range of 1 m – 1.3 m, though this can depend on factors such as temperature and humidity. Special attention should be paid when positioning the motion sensors to ensure they are not triggered while walking past the stairs. Fit your sensors according to their type:
   
   Motion sensors are interchangeable so it doesn’t matter which goes at the top and bottom of the stairs. We provide 10 m of cable with each motion sensor, giving you flexibility on how you install your stair lights. These three-core cables can be extended if required, by making an appropriate joint.

4. Once motion sensors have been fitted to the staircase, they should be connected to the control unit.
   This action must be performed whilst the unit is disconnected from the power supply!
   It is important to connect the top sensor to the terminals marked top and the bottom sensor to the terminals marked bottom.
   
   a) Decide whether you are connecting the top or the bottom motion sensor first.
   b) Note that motion sensors are supplied with tails of three-core cable, coloured red, black and green.
   For the first motion sensor, insert each core of the cable into the terminal of the corresponding colour (with due regard to which terminals are for the top sensor and which are for the bottom) and tighten the terminal screw to grip the wire securely.
   After connecting the first motion sensor, test it by temporarily connecting the power supply, according to instructions 5) to 9)
   

5. Using two core flex, connect the power supply unit to the control unit, matching the + and – terminals on both units. Note that:
   • terminals on the control unit are located on the top left, labelled + and –
   • terminals on the power supply unit are located on the top right, labelled V+ and V-. There are two sets of terminals; only one V+ and one V- should be used.

6. Connect the power supply unit to the mains, according to the diagram on the unit.

7. To test your installation, you need to connect one light to the control unit. Note that only the linear LED light strips supplied by us come with tails of two-core cable, coloured red and black. NOTE: This instruction is different for controller SCR1 and SCR2. Please follow the correct instruction for the controller you have bought.
   a) SCR1 only: Insert the black wire into one of the terminals at the bottom of the control unit marked “-” and tighten the screw to secure the wire. Insert the red wire into one of the terminals marked “+”
   
   b) SCR2 only: Insert the black wire into the terminal at the bottom of the control unit marked “1” and tighten the screw to secure the wire. Insert the red wire into the terminal marked + on the top of the driver and tighten the screw to secure the wire.
   

8. Check the motion sensor activates correctly. There are 10 LED indicators at the top of the controller:
   • The LED in position 1 indicates that the top motion sensor has been activated.
   • The LED in position 2 indicates that the lower motion sensor has been activated.
   
   Check that the correct connection has been made by activating the motion sensor and checking that the correct LED lights.

9. Disconnect the power supply from the mains.

10. Connect the second motion sensor in accordance with the colour indicators and the instructions in point 4).

11. NOTE: This instruction is different for controller SCR1 and SCR2. Please follow the correct instruction for the controller you have bought.
    NOTE: The tails supplied on each LED light strip may be extended as required for your particular installation, using 2 x 0.3 mm2 or 2 x 0.75 mm2 wire.
    a) SCR 1 only: To connect the LED lights for your Intelligent Stair Lighting system, note that the control unit has terminals labelled + and -. (See Figure 7 above)
    i) If you are using LED strip lights and wish to use the end caps supplied, ensure that both cores of wire for each strip pass through one of the end caps with holes in. Ensure the cap is the correct way round so that it can be inserted into the profile end.
    ii) Insert and secure all red wires into the terminal blocks marked as LED + on the driver
    iii) Insert and secure all black wires into the terminal blocks marked as LED- on the driver
    b) SCR2 only: all black (negative) wires should be connected to the corresponding 1-20 terminal blocks. The red (positive) wires should be connected to the common terminal block marked as “+” on the top of the controller. (See Figure 8 above)
    i) If you are using LED strip lights and wish to use the end caps supplied, ensure that both cores of wire for each strip pass through one of the end caps with holes in. Ensure the cap is the correct way round so that it can be inserted into the profile end.
    ii) Insert the negative (black) wire for each light into the terminal connector blocks, considering the numbered ordered of the lights with the corresponding marking on the controller (1-20) If you have fewer than 20 stairs, you are advised to start at number 1 for the bottom step and use consecutive terminals, corresponding to the steps that you will be lighting. It is worth labelling your wires so you know which goes to which terminal. The wires supplied may be extended as required for your particular installation, using 2 x 0.3 mm2 or 2 x 0.75 mm2 wire. Once the wires are tightened in the terminal blocks, the terminal blocks can be fitted in the controller.
    iii) Create a common positive connection for all lights, using connector clips or via any other safe means. Insert the common positive into the terminal block labelled + on the top of the controller, tighten the screw to secure the wire and connect the terminal block to the controller.
    iv) Set the correct number of steps for your SCR2 control unit to light. To set the number of steps:
    (1) The controller must be connected to the sensors, led fixtures and the power supply must be powered. Please note: a suitable main powered timer can be installed between the power supply and the mains. Please follow the installation instructions for your particular timer.
    (2) Locate the recessed reset button hidden on the upper right corner of the controller next to the indicator lights.
    (3) Push and hold the reset button for 5 seconds with a screwdriver, straightened paper clip or a similar device. The diodes blink rapidly and this will reset the driver to the default setup.
    (4) To tell the control unit how many steps are connected, press and hold the “RESET” button idden in the upper right corner of the controller next to the indicator lights, for 5 seconds.
    
    This can be done with a screwdriver or a paperclip for example.
    (5) After the reset, the unit is ready for the next instruction when the LEDs in positions A and B (see diagram below) are lit. These indicator lights, show the default number of light setting after the reset (6 stair lights).
    
    (6) To increase the number of required steps, press the “+” button, each pressing will increase the value by 1 stair (at the same time the arrangement of the information diodes will change), use the “-” button to decrease the value of the degrees.
    (7) The LEDs in the array light to indicate how many steps will be controlled, according to the following pattern:
    

12. To complete your installation, ensure the fitting of your lights is finalized.
    Disconnect the power supply from the mains while undertaking further installation works on the system!
    a) LED strip lights:
    i) If necessary, cut LED strips to length. N.B. only cut LED strips where indicated with the scissors (✂) symbol

Important note!

While cutting, drilling or making recess for the screwheads for the protective profiles, a small amount of metallic chip and debris will remain in the profile. This can cause small short circuits overdays/weeks/months and can result in the LEDs on the strips to fade out or stop working. Therefore, it is very important to thoroughly clean the profiles, before placing the LED strips inside.

i) Peel the backing from the adhesive strip on each LED strip in turn and stick them into the profiles, ensuring they are stuck firmly.
ii) Replace the diffuser in each profile.
iii) Fit end caps as required.
b) Wall recessed lights: fit your lights securely into the recess prepared earlier.
